I have a Sony A350 and have recently decided to switch over to using the ARW files from the camera in my Photoshop CS2. Unfortunately when I try to open them I get this message "Could not complete your request because it is not the right type of document". I have gone to the "Help" menu and ran "Updates..." The first time I updated I made sure that the box asking if I wanted to update to Camera Raw 3.7 was checked (which from what I understand should have fixed it). So even after installing the update why are my ARW files still not being recognized?? I'm very confused and would be thankful of any help.

Due to a recent hours cut at work I'll have to make do with CS2 a bit longer, but I'm glad you informed me of that. And thanks once again for your help. I've got DNG up and running and it's a few more steps but pretty simple getting the images into PS.
